REAR PANEL CONTROLS AND FUNCTIONS
EXTERNAL POWER JACK
The UR195 can be powered from external 12 to 18 Volts DC
applied directly to this jack, or conventional 110 VAC sources via
the supplied CH12 adapter. The UR195 is protected from reverse
polarity conditions with a diode bridge which allows external DC to
be applied without regard to polarity. If an external positive ground
power source is used, the case of the unit must be left floating and
not tied to the same common as the positive ground supply. If the
UCR195 common is tied to the common of the positive ground
supply, there are protection circuits built into the unit that will shut
the unit down before any harm is done.
AUDIO OUTPUT XLR JACK
This jack is a standard 3 pin XLR connector since this is the most
commonly used type of connector. Audio High (+) is on pin 3,
Audio Low (–) is on pin 2, and audio Common (Gnd) is pin 1.
RANGE SWITCH
The range is set by the VAR/FIX range switch (located on the back
panel.) In the VAR position the adjustment range is from –30dBm
to 0dBm, and the FIX position sets the audio output to a fixed
+8dBm with no front panel control.
ANTENNA CONNECTOR
This is a standard 50 Ohm BNC type jack for the RF input to the
receiver.
